Ant-Plant Interactions: Their Seasonal Variation and
Effects on Plant Fitness
Rico-Gray V, Oliveira PS*, Parra-Tabla V, Cuautle M, Díaz-Castelazo
This chapter discusses the importance of nectar to ants, the effect
of ants on plant fitness (either mediated by nectaries or Homoptera),
plus seasonal variation and diversity of interactions in the tropical
coastal regions of the Yucatan Peninsula and Veracruz, Mexico. Ant-plant
associations in tropical sand dunes are abundant, relative to temperate
semiarid or humid mountain sites. Studies at two coastal sites in Mexico,
La Mancha in Veracruz and San Benito in Yucatan, show significant within-habitat
seasonal variation, as well as considerable variation among habitats
in the number, diversity and seasonal distribution of ant-plant interactions.
They suggest that inter-habitat variation of ant-plant interactions
is the effect of variation in environmental parameters, richness of
plants with nectaries in the vegetation, and richness in habitat heterogeneity.

CA004-02 The Biodiversity Virtual Institute: a Brazilian
experience that can be used as model for research programs on conservation
and sustainable use of the biodiversity
Speglich E, Joly CA*
Despite increasing awareness of its importance, information on biodiversity
is not easily available. Too often, information is dispersed, fragmented,
difficult to access, not integrated with other information, out-of-date,
and underused. To help overcome such problems, in 1999 the Research
Programme in Conservation and Sustainable Use of Biodiversity of the
state of São Paulo, Brazil (BIOTA/FAPESP) and the Virtual Biodiversity
Programme (www.biota.org.br) were established. The programmes are
based on the premises contained in the Convention on Biodiversity.
The primary objective of these programmes is to study biodiversity
of the state of São Paulo. Objectives focus on: understanding
the processes that generate and maintain biodiversity; understanding
the processes that threaten biodiversity; standardizing ways to gather
and make information available to the public, policymakers and decisionmakers;
ensuring easy public access to this information; and improving teaching
standards on conservation of biodiversity and sustainable use. All
projects are linked through the environmental information system of
the BIOTA/FAPESP. This system, in turn, is linked to a 1:50 000 electronic
map of the state of São Paulo. These systems, which are freely
available on the internet, are being used by state branches in charge
of biodiversity protection and social and economic planning. Finally,
the BIOTA/FAPESP has also launched an electronic peer-reviewed journal,
BIOTA NEOTROPICA, to publish research on conservation and sustainable
use of biodiversity in the neotropics (www.biotaneotropica.org.br).
